Hello, this is my first post hope you can help. I just bought a 92 GT with several little problems door locks oil leaks etc. One problem I am dealing with now is ac blower was working intermittently so I pulled the fan resistor pack ohmed out the resistor pack with an open on the resistor. I replaced the resistor pack and now it only works on low. I pulled the motor and went straight to 12v and it blows hard. Checking the voltage at the fan connector I get battery voltage. Any help would be much appreciated.
Thank you

Low works because it travels only through the resistor pack to ground. Low speed IS essentially bypassing the blower switch

The other speeds require the blower switch to bypass resistors in the pack (or bypass it fully for high) to achieve a higher speed.

Check your blower switch. Make sure the connection is good and that you have continuity between the contacts in various positions

Here’s your blower switch testing procedure
